Tana River Delta Ramsar Site. 07/09/2012; Coast Province; 163,600 ha; 02°27'S 040°17'E. Important Bird Area (IBA). The second most important estuarine and deltaic ecosystem in Eastern Africa, comprising a variety of freshwater, floodplain, estuarine and coastal habitats with extensive and diverse mangrove systems, marine brackish and freshwater intertidal areas, pristine beaches and shallow marine areas, forming productive and functionally interconnected ecosystems. This diversity in habitats permits diverse hydrological functions and a rich biodiversity including coastal and marine prawns, shrimps, bivalves and fish, five species of threatened marine turtles and IUCN red-listed African elephant (Loxodonta africana), Tana Mangabey (Cercocebus galeritus), Tana River Red Colobus (Procolobus rufomitratus rufomitratus) and White-collared Monkey (Cercopithecus mitis albotorquatus). Over 600 plant species have been identified, including the endangered Cynometra lukei and Gonatopus marattioides. As one of the only estuarine staging posts on the West Asia - Eastern Africa coastal flyway, it is a critical feeding and wintering ground for several migratory waterbirds such as waders, gulls and terns. The main human activities include fishing, small-scale family-oriented agriculture, mangrove wood exploitation, grazing, water supply, tourism and research (ongoing research on the protection and monitoring of breeding turtles and the conservation of dugongs). Ramsar site no. 2082. Most recent RIS information 2012.
